CHENILLE-MACHINE.

To all whom it may concern Be it known vthat I, CHARLES WIEBKE, a.citizen of the United States, residing at Newark, in the county `ofEssexand State have invented certain Vnew anduseful Improvements inChenille-Machines, of which: the following is a specification,-reference' being had therein to the accompanying drawings, forming partthereof. Y

My invention relates to chenille machines and particularly tomachinesfor making ruil", or uncut chenille.' j l Objects of invention` areysimplicity and compactness of construction, time and of man1pulation'-and other objectsf andad-z labor-saving convenience and operation,vantages whichwill hereinafter appear.-

In a machine having a pluralit 4 of sets 'of loop-forming pins andfeed-regu at'ingrollers cooperative ,therewith, for concurrently makinga corresponding plurality of lengths my invention includes means forindependently vvarying the cooperative of chenille,

relationship of the feed-regulating rollers and loop-forming pins of thedifferent sets of chenille-forming mechanisms. Y

Heretofore in common practice all of a plurality of feed-regulatingrollers for all of the' correspondingl number of loop-forining pins havebeen carried by a single or common shaft extending entirely across themachine and mounted in bearing brackets adjustable onl the frame of themachine. This prior arrangement necessitates the simultaneous adjustmentand a similar relationship of parts in all of the chenilleproducingmechanisms embodied in a m chine and precludes the possibilit-y ofmaliing chenille of different sizes er of different varieties as totexture vin the different lengths thereof made concurrently or of usingdifferent kinds or sizes of material in making the different lengths ofchenille, but requires absolute unvarying uniformity in both material.and product for all of the lengths of chenille made at the same time.

It is to be noted that my invention, in the improvements above noted,entirelyI overcomes allfthese defects, permitting, among otheradvantages, the use of loop-forming pins of different diameters for thedifferent lengths of chenille.

,My invention also includes means for rewinding the bobbins which supplysurface thread to the fliers While such bobbins are v 'Specification ofLetters Patent.

Application led November i1, 1912.

in the thread-supplying chine. havehad to be removed from thethreadsupplying position-necessitating the removal of the fliers alsoandtransferred for rewinding or replenishing to a separate windingmechanism mounted on the side of or over the machine, suchinachinestaking up additional space because of the projecting winding'mechanism. Bymy present invention, this separate winding mechanism iseliminated, the entire machine is rendered more compact, and therefilling of the bobbiiis is greatly facilitated.

/Iy invention also includes other features of construction andcombinations of parts, is will appear from the following descripion. Ishall now describe the chenille machine illustrated in the accompanyingdrawings position on the maembodying my invention and shall thereafterpoint out my invention in claims.

The chenille machine illustrated in the drawings as embodying my presentinvention` is adapted to produce onlyuncut chenille, known also to thetrade as ruff and as frill, and is a double machine, having aduplication of parts for lengths of chenille at the same time. In eachof the chenille-formingmechanisms of this machine, a stationary arbor l,firmly fixed at its rear end in a supporting standard 2, removablycarr-ies'a stationary loopforming pin, such as 3 or 3*, at its enlargedforward end and in its middle portion serves as a bearing for the sleeve4 o f a flier having arms 5. The enlarged shank ofthe loopproducing twoforming pin, which enters the enlarged terminal portion of the bo-re ofthe arbor 1, is grooved (Fig. 7) for the passage of the primary binderthread a, whloh is sup lied along the surface of the projectingoopforming portion of the pin 3 (or 3*) through the' hollow arborl froma spool 6 at the rear of the machine. Loop-forming pins havingloop-forming portions of either larger or smaller diameter (the pins 3and 3* being examples of two sizes) may be interchange- ,ablysubstituted in the arbor 1 of either of the vchenille-producingmechanisms for producing chenille having correspondingl, Elonger o-rshorter surface loops, as desired, i a machine embodying my resentinvention b ]ceing particularly adapted to permit such substitution ofloop-forming pins, as hereinc' before mentioned' and as will hereinafterregulating slight, circumferential Each more particularly appear. Theloo -forming surface thread o is wound about t Vce loop# forming portionof the pin 3, and at the same time about the rimary binder thread a, bythe arms 5 of 't 1e rotating flier (only one of these arms being used ata time, the other edecting rotary counterbalancing), the surface threadc being supplied to the flier from a bobbin 7 journaled on .the sleeve 4ofthe flier. The secondary binder thread b is supplied alongtheloop-forming portion of the pin 3, at the outside ofthe coils of thesurface thread A0by a metal feedroller 8 which is driven and controlsthe coils of the surface thread 0 in their movement forwardand from thepin 3 to form the surface loops-vbthenuncut chenille, thefeed-regulating roller 8 having a roove to guide the thread b which'issupp ied from a spool 9 at the front of the machine, the thread bpassing around an intermediate tension pulley 1,0. The'feed-regulatinOY-roller 8 is also milled or provided withi-` finelongitudinal striationsvas is usual so'it can eii'ectively vperform itscoil-controlling.,operation.` My r invention involves the means formounting and drivingvthe feed-regulating rollers 8 and means forrewinding the bob- "bins 7 with thread whilefthe bobbins .are inposition on the sleevesi of the fliers.

feed-regulating roller 8 is mounted to `yield bodily away from theloop-forming passage of lumps pin 3, or 3*', to permit the Eachfeed-reguor knots in the` material.

for independently varying its coperative lrelationsl'iip withtheloop-,forming pin, to provide for the use of diderent lsizes of yarn orthread andffor the employment of looplatingl `roller is "also providedwith meansmeans of a thumb screw 14 passing loosely i through the top ofthe post and ypassing vertically through and having screw-thread edengagement with the blocjk :12.

block 12 1s provided with a lateral guide flange, as` shown ink thedrawings, on its side adjacent to the feed-regulating roller 8, but atthe oppositesidefof the post 13 a loose washer 15 is carried by a stud16 which rigidly projects from the block 12, a strong coiled spring 17being interposed between an adjusting nut'screW-threaded on the stud 16and the washer 15. Thehole at the top of the post 13 for the freepassage of the screw- .14 is laterally enlarged at the side adjacent tothe roller 8 (Flg. 4), and the head of thenscrev;7 slidably bears on thetop of the post. When any abnormal pres- ,sure comes on thefeed-regulating-roller 8,

material, the spring 17 will yield lto permit a downwardl angular bodilymovement of the feed-regu ating roller 8, thereby permitting the lum orother enlargement to pass without trouble. To provide for usingdifferent lsizes of yarn or for employing loo forming pins of diiferentdiameters, t e feed-regulating roller 8 may be raised or lowered bymanipulating the screw 14.

All o f the feed-regulatingrollers 8 (being two in number in the machineillustrated in the drawings) are driven from a single common cross-shaft'18. Each feed-regulating roller 8 is separately driven by a train ofthree intermeshing gearsl 19, 2O and 21, of

18, the gear 21 is carried by a boss or sleeve the middle gear 2() is anidler carried by the pintle 22 of pivoted ,elbow-links 23 and 24fulcrumed, respectively, on the cross-shaft 18 and the shortroller-supporting shaft 11, the pintle 22 Abeing rigidly fixed in 4oneof these links, such as in the linkY 23r- This arrangement of gearspermits the adjustment of the feed-regulating roller,herein beforedescribed, without affecting the driving thereof.

cross-shaft 18 are a counter-shaft 25 andi cone pulleys 26 and 27connected by a crossed belt 2 8, the counter-shaft 25 being driven by asprocket chain 29 from a main shaft 30, the latter being provided with afast pulley or ,driving pulley and a loosepulley 32, as is usual.

pulley 31 through the intermediary of a longitudinal shaft 33 geared tothe main shaft 30 and connected by a sprocket chain 34 with an upperlongitudinal stub shaft`35,

whichwarries a large spur gear 36 The which the gear 19 is fixedA onthefcross-shaft,U

such as by reason of a lump or knot in the l forming an extensionfromthe roller 8,'and v The means shown for drivingthe-commolr Duringthe chenille forming..operation,N the fliers 4 5 areJ actuated from thedriving,-

tively, on the sleeves 4 of the two adjacent fliers. The direction ofrotation of the fliers positions, or in the middle when viewed from thefront of the machine is counter-clockwise, as indicated by arrows inFig. 3. The surface thread c causes the bobbins 7 to rotate in the samedirection as the fliers, but somewhat faster, due to the usingI of t-hethread from the bobbins. The rotation of the bobbins 7 is controlled bya Weighted brake co-rd 38 engaging V-grooves in the rear rims or flangesof the bobbins, as is common in the art.

The mechanism for rewinding the bobbins 7 is actuated from the `loosepulley 32. A belt 39 connects the loose pulley 32 with a winding shaft40 journaled on the lower part of the frame and carrying a V-pulley 41.A lever 42 is on the frame of the machine for movementtransverselyl ofthe machine and projects above the machine by` the hand. Near itspivotal point the lever 42 has a small idler guide pulley 43 mountedthereon, and adjacent to the rear rims of the bobbins 7 the lever 42-carries a small pulley 44 whose axis is parallel ywith the axes of thebobbins 7 and whose periphery is provided with a shallow belt-groove. Around or cylindrical Winding belt 45 runs over the V-pulley 41 on thewinding shaft 40 and, being ided at an intermediate point at one sideuby the guide vpulley 43, passes upward over the small pulley 44, andprojects from the shallow roove therein in proximity to the V-groovecrear rims of the bobbins 7, but out of contact therewith when the lever42 is in its middle position, as shown in the drawings. When the usualmain driving belt 46 is shipped to the loose pulley 82, thereby stoppingthe chenilleforming operation of the machine, including the stoppage ofthe fliers 4-,-5 and the feedregulating rollers 8; to one side, thewinding belt 45 at the point where it passes over the small pulley 44will be brought grooved rim of the corresponding bobbin 7 to effect itsrewinding lwith a supply of surface thread 0,' and if the lever 42 bepulled to the other side, the other bobbin 7 will in like manner berewound. The lever 42 may be locked in either' of these bobbin-windingnon-operative position shown in the drawings, by means of a clamp 47controlled by a clamp bolt having a wing nut 48 to grip a strap 49forming also a gear cover. The thread-replenishing rotation of thebobbins 7 will be in a clockwise direction as viewed from the front -ofthe machine and as indicated by the arrow on the small pulley 44 (Fig.3), the bobbins, of course, rotating oppositely to this pulley.

To equalize the braking effect on the bobbins 7 in thechenille-producing operation,

pivoted at its lower end in aposition to be graspedif the lever 42 bepulled into contact with the peripherally the brake. cord .BSshould beanchored ata point between thebobbins 7, and inthe ma- 1,

chine illustrated ,itis shown as anchored to a stud carried bythe lever42, this point of anchorage of theV cord being merely incidental and amatter of convenience of construction. 1

Lubrication of'each iier and its bobbin, while protecting the threads oryarns, is provided for by means of a. thread-guiding tube or bushing 50(Fig. 7), having enlarged end portions which have a fluid-tight fitinthe bore of the arbor l, but in its and throughout most of its lengthbeing of smaller external diameter than the internal diameter of thebore of the arbor, so as to thereby provide an annular oil space. On itsupper side at a readily accessible point, shown as near its rear end,the arbor is provided vwith an oil inlet opening into the annular-oilspace. Within the flier sleeve 4 the arbor 1 is shownas provided withoil outlets for-.lubricating such sleeve, the latter also being providedwith oil passages or perforations adapted to register or communicatewith the oil outlets in the arbor 1 for lubricating the bobbin 7 whichcovers the oil passages in the sleeve 4. Both theprimary binder threada, passing. through the' arbor l, and the surface thread c, carried bythe bobbin 7, are by means of this construction completely protectedfrom the oil used for lubricating the flier and bobbin.

T e tension pulleys 10 that control the feed of the secondary binderthread b are fixed on a transverse shaft 51 driven at the proper rate bymeans of a gear 52 and intermediary idler pinion 53 from the feed shaft18' for the feed-regulating rollers 8. The transverse shaft 51 alsocarries a conepulmiddle portion ley 54 for propelling the usual trolleyemployed to carry away the lengths of chenille as fast as formed. Alarge cone pulley 55, shown in the drawings as mounted on acounter-shaft 56 driven from the main shaft 30 by means of a sprocketchain 57, is for driving the usual twisting spindle ofthe trolle whichtwists the chenille to bring out the surface loops formed from thesurface thread c and to bind'these loops between the bind," threads aand b.

A few of the more prominent advantages of -the hereinbefore Vdescribedmachine embodying my invention will be briefly noted.

For each chenille-forming mechanismdifferent sizes and kinds of yarn orthread may be used andtalso different sizes of loop-forming pins may beemployed to produce correspondingly different sizes and textures ofchenille by the operation of each chenilleproducing mechanism,irrespective of the operation of any other chenille-producing mechanismin the machine. The bobbins carrying the loop-forming surface thread oryarn may be quickly refilled Without'thc usual,- necessity ofA having toremove vthem from their operative thread-supplying position on thefliers, and the fliers. and bob bins may be properly and safelylubricated -vvhile in theiry operative positions with the threads oryarns 1n place for producingv ms, a glinding a surface thread on theloop-forming pin, a separate feed-regulating roller cooperative Witheach loop-forming pin to control the movement of he coils of thesurf-aceA thread therefrom, independent means for varying the coperativerelationship of each feed-regulating roller and its loop-forming pin,the feed-regulating rollers.-
